To all whom it may concern: Be it known that I, HENRY F. BEGHMAN, ofBattle Oreek,vin the county ofCalhoun and State of Michigan, haveinvented certain new and useful Improvements in Ink- Fountains forPrinting-Presses; and I hereby declare that the following is a full,clear,

' and exact description thereof, reference being had to the accompanyingdrawings, which form part of this specification.

This invention is a novel improvement in the construction of inkfountains for printing presses, and its objects'are to insure the exactaxial alinement of the bearings of the fountain roll in the fountain toenable such bearings to be turned and faced apart from the fountaincasting, and then positioned therein; and 'to insure a close true fitbetween the inner ends of the bearingsand the adjacent ends of thefountain roll to prevent any leakage or waste of ink from the fountainaround the bearings at the end of the roll. e

Another important object of the invention is economy of manufacture.Fountains made in this manner cost much less to build and assemble,besides being much more perfeet and satisfactory in construction.

I will explain the invention with reference to the accompanyingdrawings-which illustrate one practical embodiment thereof.

In said drawings Figure 1 is a top plan view of .a portion of an inkingfountain shaped fountain body] or casting, which maybe of any desiredusualconstruction, having thickened end walls 1 in which the fountainroll journal bearings are mounted. The end walls 1" of said fountain arepreferably bOIBCljOIlt to form openings or pockets for the j ournalbearings and .when these'pockets are circular they should be slightlylarger in diameterthan the diameter of the fountain roll 3. Such pocketscan be bored simultaneously in a suitable machine so that the twopockets will be in exact axial alinement. The pockets when circularshould be slightly rollwill becprreetly positioned in the foun the endsof the fountain roll and the founof each bearing for engagement by tapbolts '4, which are passed through holes 1 in the larger in diameter thefountain roll- 3, I so'that the lattercan be readily inserted inposition in the fountain by passing it endwlse through the said pockets.

The fountain roll. is provided with-tru'n-' .nions or journals 3 atits'end's, and after sald roll has been placed inposition in thefountain, the journal bearings 2, which are suitably bored to fit thetrunnions 3,- can be slipped endwiseioverthe latter; Said journalbearings are adapted to closely fit in the pockets in the end walls 1.After the bearings have been'slipped'on the fountain roll journals (whenthe pockets and bearings are circular) the bearings can be pressedendwise into the pockets in the fountainend- Walls; and when so,positioned the fountain tain, and the bearings be truly axially alined.v The journal bearings 2'can' be machined prior to their insertion inthe fountain ends;

and the inner ends of said bearings should be plane-surfaced, so thatthey will fit accurately and closely against the ends of the fountainroll 3.

With the old method of mounting the rolls in the fountains the ends ofthe roll would be more or less out of square with the inner surface ofthe fountain end-walls and th ere fore in a short time ink would workbetween tain walls and thence out through the bear ings. And as thesurfaces became worn this would increase and considerable annoyancewould be caused, and there was no means for remedying this condition.Such leakage is entirely eliminated by my method of mountingthe fountainrolls.

In order to secure the bearings in position I prefer to form threadedsockets in one side end walls 1* and screwed into such threaded sockets.The-holes 1", in the fountain walls, through which thesetap bolts pass,are preferably made slightly larger in diameter than 1 00 the bolts toenable the journal hearings to be adjusted endwise in the pocketsv forthe purpose of taking up the end motion on the fountain roll when itbecomes slightly worn.

' By tapping the bolts 4 into the journal bearings, to clamp the latterto the fountain, I

obviate the danger of cracking or breaking the fountain end-Walls, whichset screws tapped through the Walls might do.

The advantages of'this invention are,- economy of construction; facilityof finishing the parts of the fountain; simplicity of assemblagethereof; accuracy of fit; ready compensation for Wear; and economy inre-' pairs. These advantages of the invention might be obtained in otherembodiments of the invention than that herein illustrated which howeverI prefer because when the pockets are simultaneously formed, by a propermachine, in the end-Walls they are in perfect alinement, one withanother, and consequently the bearings for the fountain roll Will betruly alined When they are placed in these pockets.

What I claim is:

1. In combination With an ink fountain having axially alined openings inits end Walls slightly larger in diameter than the fountain roll; afountain roll adapted to be inserted through said openings into thefountain; journal bearings for the roll adapted to be slipped endWiseover the journals of the roll and ,forced endWise into the saidopenings; and setting bolts passed through holes in the end-Walls andscrewed into threaded sockets in the adjacent bearings to I secure thelatter in position.

2. In combination With an ink fountain having axially alined pockets ,inits end- .Walls of greater diameter than the roll, a

fountain roll, and journal bearings for the roll of larger diameter thanthe roll and corresponding to the pockets and adapted to be slippedendWise over the journals of the roll and fitted into the said pockets;and

setting bolts passed through holes in the for the roll having partscorresponding in external contour to the internal'contour of the saidopenings and adapted to be slipped endWise over the journals of the rolland forced endwise into the said openings to close the same and positionthe roll in the body, and means for fastening said bearings in saidopenings' In testimony that I claim the foregoing as my oWn, I aifix mysignature in presence of two Witnesses.
